FIXTURE ANCHORAGE.

Application filed Julie 10, 1927. Serial No. 197,878. 1

Our invention relates to improvements in devices for anchoring fixtures such as kitchen or bathroom fixtures to walls, and it consists in the combinations, constructions, and arrangements herein described and claimed.

Considerable difliculty has been experienced in mounting fixtures such as plumbing fixtures, kitchen sinks and lavatory basins, upon walls or partitions, due to the fact that the weight of these fixtures is apt to cause them to pull away from the wall. Attempts have been made to anchor devices of this kind, by embedding wood blocks in the wall and to screw the holding devices, such as sink brackets, to this. The use of wood blocks requires considerable care or it will show on the finished plaster above the sink. The plaster will not readily trowel over the block, since the blocks are not usually provided with keys.

An object of our invention is to provide an anchorage which forms a firm support for plumbing fixtures oi' the type mentioned and which allows for a good smooth surface of plaster which will not crack or fall away from the anchor.

A further object is to provide an anchorage which may be used in connection with ordinary wood screws or with toggle bolts.

A further object is to provide an anchorage of'the type described which permits the screws or bolts to be put at varying positions without the necessity of shitting the anchorage.

A further object is to provide an anchor construction which is all metal, but which provides for a good thread for a wood screw at any position selected.

A further object is to provide a wall anchorage structure which actually reinforces the wall at the point of suspension.

Other objects and advantages will appear in the following specification, and-the novel features of the invention will be particularly pointed out in the appended claims.

' Our invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a front View of a wall portion showing the anchoring device, a portion of the wall being broken away,

Figure 2 is a vertical section along, the line 2-2 of Figure 1,

Figure 3 modified form of the device, 7

Figure 4 is an enlarged vertical section of a portion a Figure 5. is a face view ofa back plate. In carrying out our invention, we make use of a metal plate 1 made in the form of.

a grille; that is to say, havingiopenings 2 therethrough. In Figure 1, we 'haveishown these openings as being square, although they may be other shapes withoutdeparting from the spirit of the invention. Thismemher 1 has at the back thereof a sheet 3. of

galvanized iron and next to it a strip or layer of sheet lead The back is formed oi a sheet of galvan zed iron 5 whoseedges are bent; over theedges of the other sheets and or the body portion and around on the beveled front portion .1 of the grille 1, as shown in Figures 1 and 2. The grille-is provided with bolt openings for receiving staples 6 such as that shown in Figure 2.

In Figure 2, we have shown a section of a wall in which a metal lath 7 is secured on each side of studding 8, the studding in this instance being angle iron. Bolts 6 extend through the plates 3, a and 5 and through a backing plate 9 adjacent to the metal lath 7, the nuts 10 of the bolts 6 being embedded in plaster 11. It will be understood that this means of securing the grille in position is merely typical of many means that mightbe used. The grille itself is beveled at its edges as has been already explained and it is covered with plaster 12 so that it is hidden from view. The openings in the front face of the grille permit plaster to enter sothat the outer coating which covers the grille may be thin and yet may be readily troweled and when applied will stay in position.

From the foregoing description of the va-.

rious parts of the device, the operation thereof may be readily understood. In Fig ure 2, we have shown a portion of a bracket 13 having a socketl l for receiving a portion of the device to be supported. The bracket may be secured to the anchor by ordinary wood screws such as that shown at 15 in Figures 2 and l. In this instance, a hole is is a Vertical section through a of the device shown in Figure 2,,

punched through the plaster in the recesses of the grille and through the plates 3, 4 and 5 and the screw is placed in position and turned as far as it Will go. We have found that with the lead plate enclosed in between the galvanized ironplates, the screw will find a firm anchorageand will make its own threads so that it can be drawn up tightly.

Instead of using screws, we may use. tog gle bolts, such as that shown at 16 in Figure 3. In this instance, a hole is made through the plaster in the recess of the grille and through the plates 3, 4 and 5 and the pivoted portionof the toggle bolt isinserted and the bolt is drawn tight against the bracket 13. i i

,A fixture anchorage such as that described has numerous advantages. It can be made without defacinga wall, and in fact it reinforces thewall at the point where it is applied. It can be plastered over and the screws or bolts for holding the bracket may be placed in difi'erent positions if one position. is more desirable than another. This construction provides for a firm hold for the wood screw as well as for toggle bolts. It is readily installed at acomparatively slight, cost. a

.We claim:

' p ,1. A fixture anchorage, comprising a body and holding a wood screw, said last-named means comprising a pair of sheet. metal plates and a sheet of softer material disposed between said metal plates for spacing them apart. a n

2. A fixture anchorage, comprising a body portion in the form of a grille, means for securing said body portion to a wall, a plurality of metal plates covering the o enings at the rear of the grille, the openings in front of said sheet metal plates being adapted to receive plaster,bracket holding means, and means for securing said bracket holding means to said plates, said lastnamed means 'being arranged to project through said openings and through said metal plates.

3. A fixture anchorage, comprising a body portion in the form of a grille, means for se curing said body portion to a wall, a plurality of metal plates covering the o )enlngs at the rear of the grille, the openings in front of said metal plates being adapted to receive plaster, bracket holding means arranged to project through said op'enings and through said metal plates, and means for securing said bracket holding means to said plates.
